What four conditions do bacteria need to survive
- Food usually found in fridge
Bacteria prefer to grow in foods high in protein vitamins and minerals eg milk chicken ham and fish
2.Moisture
Bacteria need moisture to grow and therefore cannot multiply in dry foods .Once dry food is reconstituted (water is added )then the food becomes ideal breeding ground for bacteria eg custard powder packet soup pot noodle
3,Warmth
Bacteria like to be kept warm multiply in warm conditions.
64 -100c destroyed
5-63 c DANGER zone
1-4 c bacteria multiply slowly
-18c bacteria dormant ( inactive -alive but not growing or multiply) - Time
